QUILTING-MACHINE.

SPECIFICATION forming part of Iietters Patent No. 279,632, dated Jun-e 19, 1883.

Application filed March 19, 1883.

To all whom it may concern,.-

Be it known that I, AUGUST BECK, of the city, county, and State of New York, have invented certain new and useful Improvements in Quilting-Machines, of which the following is a specification.

This invention has reference to improvements in quilting-machines of that class in which a needle-bar with a single gang of needles is employed, and in which the fabric to be quilted receives a straightforward motion alternately with a compound forward and laterally-reciprocating motion; and the invention consists of the combination, with a laterally reciprocating carriage supporting an organized sewing mechanism, with a verticallyreciprocating needle-bar having a single gang of needles, of mechanism whereby laterally-reciprocating motion is imparted to the carriage, mechanism for throwing the latter mechanism in or out of gear with the driving-shaft, of rollers mounted on the stationary frame for moving the fragment intermittently forward, operated by any suitable mechanism, and details of construction which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l represents a sectional front elevation of my improved quilting-machine. 2 is a plan of the same with parts broken away. Fig. 2 is a detail vertical transverse section of thecarmage-actuating mechanism on line i/ y, Fig. 2. Fig. 3 is a vertical transverse section on line .f1-, Fig. 1. Fig. 4 is a diagram plan of the cam by which laterally-reciprocating motion is imparted to the main part or carriage of the quilting-machine, and Fig. 5 shows the pat-- tern or design to be quilted on the machine;

Similar letters of reference indicate corresponding parts.

A in the drawings represents the supporting-frame of my improved quilting-machine, which frame is made of oblong shape.

On the horizontal top part of the frame A is supported, on anti-friction rollers b b, a laterally-reciprocating carriage, B, upon which are supported a vertically-reciprocating needle-bar, C, and a needle-plate, with the shuttles and their actuating mechanism. The rolls D for feeding the fabric are mounted on standards shown in dotted lines, and supported by (No model.)

the frame A. The shuttles and the shuttledriving mechanisms are not shown inthe drawings, as they are the same as in other quiltingmachines having a needle-bar with a single gang of needles. The carriage Bis guided by means of longitudinal slots b on vertical guideposts b, of the main frame A.

The mechanism by which vertically-recip rocating motion is imparted to the needle-bar C is actuated by the main driving-shaft E,which receives rotary motion by a belt-and-pulley transmission in the usual manner.

Any approved mechanism for imparting vertically-reciprocating motion to the needlebar C, also any approved mechanism for imparting intermittent rotary motion to the fe'ed.- rollers D D, may be employed. The mechanism for reciprocating the needle-bar C consists of a crank-disk, e, at the end of the drivingshaft E, a connecting-rod, c', and a crank, c2, at the end of a rock-shaft, ci, supported in bearings at the upper vends of standards B, secured to the carriage B, t-he rock-shaft c being connected by fixed cranks e* and connecting-rods e5 with the fixed vertical guide-rods o of the needle-bar (l, said guide-rods sliding in sleeves e7 of a transverse stiffening-bar, c, as` shownclearly in Fig. 1.

The mechanism for transmitting intermittent rotary motion to the feed-rollers D is, for the sake of greater clearness, not shown in the drawings.

The shaft E is made in two sections that are connected by a suitable coupling and sleeve,

El, at one side of the carriage B, said coupling being so arranged that that section of the .shaft E above the carriage B is capable ofA a .C to the feed-rollers D, as shown clearly in Fig.

For producing reciprocating motions there is arranged at one end of the machine an auX- iliary guide-plate, G, which is pivoted at gto the reciprocating carriage B. Through alon- IOO gitudinal center slot, g', of the guide-plate .G (see Fig. 4) passes avertical shaft, 71 that turns in suitable step-bearings, h', of a transverse base-plete, G', that is guided by slots g2 on Xed studs g3 of frame A, below plate G, and in neckbearings h2 of a bracket-plate, G2, attached to the base-plate G. The shaft h carries an cccentric pattern-cam, lr, of special construction, which cam is shown in detail in Fig. 4, and above the same a worm-wheel, 71,", which latter meshes with a worm, h5, on that section 1 E of the driving-shaft E that does not participate in the laterally-reciprocating motion that is imparted to the carriage B of the sewing mechanism. The circumference ofthe eccen tric cam hais divided into as many equal parts as there are stitches to be made in eachindividual zigzag, diamond, wave-line, or other figure, the cam being for this purpose of symmetrical shape, so that one half of the cam makes the stitches of one half of the figure, the other half of the cam the stitches of the other half of the individual figure. 'Each of the parts into which the circumference of the cam is divided is again divided into iive parts, four of which, form arcs concentric to the axis of the cam, while the fifth part is arranged at an outward angle thereto, and connects the concentric are of one part with the arc-shaped portion of the next adjoining section of the cani, as shown clearly in Fig. 4. The cam 71 engages anti-friction rollers 71th, which are arranged equidistantly from the shaft h on the pivoted guide-plate G, so as to impartthereby, by the action ofthe cam, reciprocating motion in one or the opposite direction to the carriage B, on which the sewing mechanism is supported. The laterally-reciproeating motion of the carriage B, however, only takes place when the worm-wheel 71,4 is in mesh with the worm lz, on the driving shaft E. Vhenevcr the worm and worm-wheel are thrown out of engagement with each other, the reciprocating motion is interrupted and the carriage stopped. This is accomplished at the pleasure of the operator by means of a hand-lever, 71, connected to the base-plate G,which lever moves the base-plate G as far as its guide-slotsgl permit. The worm-wheel l14 is thereby thrown out of gear with the worm hf', the laterally-reciprocating motion that is imparted by the cam to the carriage of the sewing mechanism interrupted, and thereby the quilting of the' fabric changed back again from figured stitches to straight parallel lines of stitches, as shown in Fig. 5.

The mechanism for throwing the wormgear in or out of mesh with the worm is operated by hand, the. pointer hl on the upright shaft h indicating, bythe number of its revolutions, the number oi" individual figures, whether they l be zigzag, diamondwaif'es, 85e., that have been quilted on the machine. By properly counting these revolutions the attendant is enabled to throw the intermeshing worm and wormgear at the proper moment in or out of gear, so as to cause the quilting of the fabric in alternating straight and in figured lines, as required by the pattern to be produced. lf it be desired not to leave this to the attendant, a 7o special mechanism may be provided, by which this work is performed automatically by the action of the machine, which mechanism, however, is not shown in the drawings.

By my improved quilting-machine, skirts or other fabrics can be quilted with a continuous line of stitches that alternate with gured stitches at the proper points. Fabrics so quilted have the advantage that they present a neater and more finished appearance than fabrics that are quilted in the same ligure over a partor the entire body of the fabric. Y

I have made a special application for Letters Patent for a design for skirts and other garments quilted in this manner, which has been filed at or about same date herewith, and to which reference is made.

Having thus described my invention, I claim new and desire to secure by Letters Patentl. The combination of the supporting-frame A, having rollers b b, a laterally-guided carriage, B, carrying a series of Organized sewing mechanisms, a guide-plate, G, having rollers 116, a transversely-guided plate, G, carrying a bracket, G", a vertical shaft, lz., eccentric pattern-cam lf', transmitting worin-gear 7L* 71,5, and a lever mechanism for sluiting the transverse plate G and throwing thc transmitting worm-wheel in or out of mesh with the worm on the driving-shaft E, substantially as specified.

2. In a quilting-machine, the combination, with a laterally-guided carriage, B, supporting a series of organized sewing mechanisms, cfa centrally-slotted guide-plate, G, pivoted to the carriage B, said guide plate having anti-friction -rollers 71, a transversely guided pl atc, G, having a bracket, G2, averti cal shaft, 71, having a pointer, lll, and turning in bearings of pla-te G and bracket G2, eccentric pattern-cam la, engaging rollers h, gear-wheel 71.4, worm-wheel 715, and lever mechanism for shifting the transverse plate G, substantially as set forth.

ln testimony that l claim the foregoing as my invention ll have signed my name in presence of two subscribing witnesses.
